A new miniature dual behavior resonator (DBR) topology with capacitors placed in series between the feed lines and the stubs is demonstrated. Design equations are derived. For a proof‐of‐concept, a first‐order prototype with a 1‐GHz working frequency and 70% size reduction is realized, measured, and compared with a classical DBR. The design method is simpler and more accurate compared with a miniaturized DBR with capacitors connected at the end of the stubs. Hence, the agreement between simulation and measurement results is better than previously published results of a miniature DBR using capacitors at the end of the stubs. Results also point out a quality factor improvement of 12%. © 2010 Wiley Periodicals, Inc. Microwave Opt Technol Lett 53:278–281, 2011; View this article online at wileyonlinelibrary.com.
